The man who kidnapped William

Hearing a long explanation from Dani made Lisa's sobs stop for a moment. The woman moved her face away from Oscar's chest then looked at the male assistant with reddened eyes.

"Then who kidnapped my child!? Have you found out the mastermind behind all this?"

"I'm still trying to get information from local residents because the CCTV footage around William's school didn't show the face of the person." 

When Dani finished explaining, Lisa's cell phone rang. The woman's frantic attention immediately fell on her cell phone's screen, which showed a row of unknown phone numbers. 

"Try to pick up the phone, who knows he's an important person." Oscar urged as he felt Lisa would reject the call. As long as he knows her, she won't receive calls from numbers she didn't save before.

"Hello?" Lisa said in a hoarse voice.

"Good afternoon, Lisa!"
